Car interior sound-absorbing cotton is a commonly used car sound insulation material, the main function is to absorb the noise in the car and reduce the transmission of noise in the car. The sound absorption effect of sound-absorbing cotton depends on many factors, including the density, thickness, sound absorption coefficient and installation method of the material. The following analysis of the effect of automotive interior sound absorption cotton.

The sound-absorbing effect of the sound-absorbing cotton of the car interior is related to the density and thickness of the material. Generally speaking, the higher the density and the greater the thickness of the sound-absorbing cotton, the better the sound-absorbing effect. This is because the sound-absorbing cotton with high density and thickness can better absorb sound waves and reduce the transmission of noise in the car. At the same time, the high-density sound-absorbing cotton can also reduce the resonance of the metal parts of the body and further reduce the noise in the car.

The sound-absorbing effect of sound-absorbing cotton for automobile interior is also related to its sound-absorbing coefficient. The sound absorption coefficient is an important index to measure the sound absorption ability of sound-absorbing materials, which is related to the density and thickness of the material and the thickness of the air layer. Generally speaking, the higher the sound absorption coefficient, the better the sound absorption effect. Therefore, when choosing sound-absorbing cotton for automotive interior, materials with high sound absorption coefficient should be selected.

The installation method of the car interior sound-absorbing cotton will also affect its sound-absorbing effect. Generally speaking, the sound-absorbing cotton should be evenly pasted on the metal parts of the car, such as the roof, floor, side walls and other parts. At the same time, avoid the formation of bubbles or voids when pasting, so as not to affect the sound absorption effect.

It should be noted that although the car interior sound-absorbing cotton can effectively reduce the noise in the car, it cannot completely eliminate the noise. Therefore, when using sound-absorbing cotton, it should be selected and installed according to the specific conditions of the vehicle to achieve the ideal sound-absorbing effect.

In short, car interior sound-absorbing cotton is a very effective car sound insulation material, which can effectively absorb noise in the car and reduce the transmission of noise in the car. However, when selecting and using sound-absorbing cotton, attention should be paid to the density, thickness, sound-absorbing coefficient and installation method of the material to achieve the ideal sound-absorbing effect. At the same time, it should be noted that sound-absorbing cotton cannot completely eliminate noise, so you should pay attention to the reasonable use and collocation of other sound insulation materials when using it.
